What kind of onions do you grow? I’ll try regular onions (as opposed to walking onions) next spring and have at least one envelope of onion seed, maybe two, but don’t have any info. as to whether they will be good for Texas.
I've opened up a little more than 300 sq ft in mostly shade for the tobacco next year. The soil is sandy and lacks much in the way of biomass.
I decided to put winter wheat in there for ground cover and till it in next spring for green manure. This is one of the very few times that I'm using commercial fertilizer on my property.
I did broadcast the wheat pretty heavy. Over a quart for 300 sq ft. ;)
